ERNEST HAMILTON HEINKE, OF LONDON, ENGLAND.

BOAT-PROPELLING MECHANISM.

To all whom it may concern:

Be it known that I, ERNEST HAMILTON HEINKE', a citizen of the UnitedKingdom of Great Britain and Ireland, and resident of 54 South Moltonstreet, London, England, have invented certain new and usefulImprovements in Boat-Propelling Mechanism, of which the following is aspecification, such as will enable others skilled in the art-to which itappertains to make and use the same.

This invention relates to motors and propellers for attachment to boatsand other floating bodies andrefers to that type of machine in which aninternal combustion engine or other motor arranged above the waterlineis adapted to drive a vertical shaft, the lower end of which is in gearwith a propeller below the water line.

, The invention concerns particularly a better arrangement for mountingthe appliance upon the boat or other floating body where by it can beentirely raised from the water and placed upon the deck or equivalent ofthe boat. r

The invention also includes details of construction relatingparticularly to the arrangement for steering, the brackets emloyed formounting the motor andaother eatures hereinafter described and claimed.

In the accompanying drawings, Figure 1 the bracket for supporting themotor in operative position, and Fig. 6 is a plan of the same when inthe position of Fig. 5.

Referring to Fig. 1, the motor T is attached by means of bracket Randscrew W to the stern or transom N of the boat. The motor drives pinionwhich is in mesh with pinion P on the vertical shaft B, the said shaftbeing inclosed in the hollow shaft E and having at its lower end thepinion J in meshwith pinion K on shaft L to which the propeller isfixed. Pinions J and K are contained in the gear case A which has anextension C in line with the hollow shaft E Specification of LettersPatent.

and is adapted to be turned by means of a cog wheel F which is keyed tothe extension C and is in mesh with the wheel G 'on the shaft S, thesaid shaft being adapted to be turned by any suitable means such as aflexible shaft to which it may be connected.

It will be seen from Fig. 2 that the wheel F is keyed to the sleeve orextension C and .it will be obvious that if the wheel G is turned byshaft S it will rotate wheel F and thereby swing the propeller aroundand thus enable the boat to be steered, or driven astern.

The wheels F and G are inclosed in the case H to which the V-shaped orangle bracket. N is pivotally fitted, the said bracket being composed oftwo symmetrically disposed members each consisting of an inner partpivoted at its inner end to the pivot U' and resting, When' in operativeposition,

with its lower part on the stop V on the stern of the boat. Whenthe'appliance is moved' from operative to inoperative posi. tion, thewhole appliance is swung over onto the deck,'the. bracket M pivoting onthe pivot U.

In Fig. 3 the steering and reversing gear is arranged close to the motorand the drawing clearly shows how the appliance can rest on the deck Zof the boat.

'-In Fig. 4 links R pivoted at R to the motor and at R to brackets onthe deck Z' are used in place of the bracket and screw R, W, shown inFig. 1."

It will be observed that the peculiar formation of the bracket M permitsthe appliance being turned well over on to the deck and also that theshape of the bracket allows the propeller to be swung completely aroundand placed under the bracket for driving astern in addition to which theforward drive of the propeller is conveyed in very direct manner to theboat.

Obviously instead of placing the appliance on the deck it can bereceived upon any suitable upport.

What I claim and desire to secure by Letters Patent is:

1. In a. boat propelling mechanism, the combination of a motor; apropeller operatively connected thereto; a link pivotally connecting thepropeller to the boat; and a loigk piyotally connecting the motor to the2. In a boat propelling mechanism,-the

combination of a motor; a propeller operatively connected thereto; and apair of links, one above the other, pivotally connecting the motor andpropeller to the boat.

3. An appliance for use with boats comprising an outboard motor and apropeller, a pair of pivoted links supporting the motor and a pivotedbracket of substantially double V shape supporting the propeller, a

shaft between the motor and the propeller, a toothed gear on the motor,a toothed gear on the propeller, a toothed gear on the upper end of theshaft co-acting with the toothed gear on the motor, a toothed gear onthe lower end of the shaft co-acting with the toothed gear on thepropeller, and means whereby the propeller can be rotated around theaxis of the shaft.

4. An appliance for use with boats comprising an outboard motor and apropeller, a pair .of pivoted links supporting the motor and a pivotedbracket of substantially double V shape supporting the propeller, saidbracket extending from its supporting point of the propeller to stopsfixed to the boat and upwardly therefrom to the pivots whereby it isconnected to the boat, a shaft between the motor and the propeller, atoothed gear on the motor, a toothed gear on the propeller, atoothedgear on the upper end of the shaft co-acting with the toothed gear onthe motor, a toothed gear on the lower end of the shaft co-acting withthe toothed gear on the propeller, and means whereby the propeller canbe rotated arour the axisof the shaft.

5. An appliance for usewith boats com prising an outboard motor andapropeller, bracket supporting the motor and a brack pivoted to the boatand the propeller, shaft between the motor and the propelle a toothedgear on the motor, a gear on tl upper end of the shaft co-actingtherewit shaft for rotating said toothed gears on tl sleeve. to effectthe turning of the propelle 6.. An appliance for propelling boats conprising a motor, combined with and adap' ed to drive a propeller, thesaid applianc being connected to the boat by means of V-shaped bracketand links pivoted to tl appliance and to the boat whereby the a pliancecan be raised and swung over 1 rest upon a support in the boat.

In witness whereof I have hereunto s1 my hand in presence of twowitnesses.
